Patented May 29, 1934 UNiTED STATES BINDING STRIP FOR USE IN THE CON- STRUCTION OIT' CASES, BOXES, CRATES, GR THE LIKE CONTAINERS F TIMBER OR THE LIKE Hermann Hans Johannes Kruse, Hemelingen, near Bremen, Germany, assigner to No-Nail Cases Proprietary Limited, London, England, a company of Victoria, Australia Application May 12, 1933, Serial No. 670,806 In Great Britain June 30, 1932 4 Claims.

Boxes are well known, in which two sides, the bottom and also in some cases the top are bound and hinged together by means of hanged metal strips attached to the box parts along the edges,

5 so that the three or four hinged parts can be folded up into the position they occupy in a box, and two end parts added to complete the box. The end parts are sometimes carried in channels or grooves provided between the end edges of the bound box parts and the flanges of the binding strips` Binding strips for this purpose, of channel cross section are also known, in which one edge of the strip consists of teeth, and the other edge consists of a bent up iiange, the teeth serving for attaching the strip to the box parts.

According to the present invention a toothed binding strip provided with a ange has the teeth cut out of the body or flat portion of the strip and between the edge oi the strip and the ange. 2O These teeth are set perpendicular to the fiat portion and preferably in aline parallel to the flange of the strip, a continuous border of metal being left between the base of the teeth and the edge of the flat portion.

The teeth project on the same side of the lat portion as the ange.

The invention is illustrated in the accompanying drawing in which Fig. l is a perspective view of a portion of a strip.

Fig. 2 shows on a smaller scale four box parts attached together by a pair of these strips.

Fig. 3 shows the box completed with the end pieces.

In Fig. l, the strip has a at portion a and a fiange b. From the flat portion are cut out and struck up teeth c, c, standing between the iiange b and the other edge of the dat portion. Onto a pair of these strips are laid, as shown in Fig.

4o 2, the box parts ci, e, f, g and the teeth c are pressed into them by rolling, spaces as shown at h being left in known manner between the iianges b and the box parts to receive the two end parts z', .1c as shown in Fig. 3.

The strip here shown has the advantage over known toothed binding strips, in that the strip can be somewhat narrower, owing to the teeth being cut from the body of the strip and not extending from its edge. Moreover the smooth border a improves the finished appearance of the box. A further advantage is that the teeth stand up better to the rolling-in operation, because they do not rise from the edge, but from between the edges of the iiat portion a. One end of each of the straps is provided with a reduced portion m arranged to extend through a complementary opening n in the other end and be bent down over the adjacent side when the box is assembled so as to retain the insertable sides i in position.

I claim:

1. In combination with a box having xed sides and insertable ends, a metal binding and hinged strap having a flat body portion provided with teeth struck out from the material between the opposed edges thereof, a flat border iiange extending at right angles to the body portion and on the same side as said teeth, the sides of the box being connected to the body portion by said teeth and having their ends spaced from said iiange to provide an uninterrupted groove which, when the box is assembled, receives the insertable ends, one end of the strap having a reduced portion and the opposite end provided with a slot for receiving said reduced portion whereby to retain the sides and ends of the box in position.

2. In combination with a box having xed sides and insertable ends, a metal binding and hinged strap having a flat body portion provided with teeth struck out from the material between the opposed edges thereof, a flat border i'iange extending at right angles to the body portion and on the same side as said teeth, the sides of the box being connected to the body portion by said teeth and having their ends spaced from said flange to provide an uninterrupted groove which, when the box is assembled, receives the insertable ends, and means for connecting the ends of the strap.

3. A folding box-blank adapted for the construction of a box having nxed sides and insertable ends, comprising two opposite sides and a bottom to form a substantially polygonal box, said sides and bottoni being bound and hinged together by means of metal binding and hinging straps having a fiat body portion provided with teeth struck out from the material between the opposed edges thereof and a iiat border ange extending at right angles to the body portion and on the same side as said teeth, the sides and bottom of the box being connected to the body portion of said strap by said teeth and having their ends spaced from said ange to provide an uninterrupted groove which is ,m5 adapted to receive the insertable ends when the box is assembled.

4. A folding box-blank adapted for the construction of a box having xed sides and insertable ends, comprising two opposite sides and a 110 intervals to facilitate the folding of the blank, the sides and bottom of the box being connected tothe body portionv of said strap to provide an uninterrupted groove which is adapted to receive the insertable ends when the box is assembled, and means when the box is assembled for maintaining the insertable ends in position.
